Hi guys, I have recently joined the TT gang with a 99 225 APX. I previously had A3 8L 1.8t sport which I had remmaped to about 215bhp. I was expecting the tt to be pretty much on par being a 225 obviously allowing for the 4wd etc. but the tt seems to be far from it. I was checking the boost and have found that it hits 1bar but at about 4000 rpm it seems to drop off to 0.5bar. im not sure if this is how it is meant to be or weather there is a problem? I have had a look around the engine bay... all pipe work seems ok, I have taken the dv off and it is holding when I put my finger over the top of it. the only thing I will be changing is the air filter as it has a cone not the standard airbox.. but I cannot see this making that much difference? am I looking for a problem that isn't there?
